Visiting Boston this fall can stroll along the Charles River, enjoy a ride on the Swan Boats, or simply relax in the Public Garden for a glimpse of autumnal color. Lush foliage, sprawling grass, and sounds of nature in these serene spots allow travelers to forget they are in the midst of a bustling city.
